摘要： A process for producing a calcium phosphate reactant, according to which: in a first step, use is made of a source of calcium and a source of phosphate ions in water, in a molar ratio that is adjusted so as to obtain a Ca/P molar ratio of between 0.5 and 1.6, and the source of calcium is reacted with the phosphate ions at a pH of between 2 and 8, in order to obtain a suspension (A) of calcium phosphate, and in a second step, added to the suspension (A) are an alkaline compound comprising hydroxide ions in order to set a pH of more than 8 and an additional source of calcium in order to obtain a suspension (B) of calcium phosphate reactant having a Ca/P molar ratio of more than 1.6.A calcium phosphate reactant obtainable by such a process.

摘要： A device for distributing a fluid in a controlled manner, in particular for distributing a gas loaded with particles, the device comprising a pipe (1) provided with at least one inlet orifice (2) and with a series of outlet orifices (3) spread along the pipe (1) and cut in a side wall of this pipe, wherein at least one section (4) of the side wall, located downstream of at least one outlet orifice and limited by a section (5) of the edge of the outlet orifice (3), has a concave shape such that this section (5) of the edge of such outlet orifice (3) is positioned inside the pipe so that, when the device is in service, the flow direction of a fluid exiting such outlet orifice (3) and travelling along such deformed concave wall section (4) of the edge of this outlet orifice (3) is controlled by the shape of such section (5) of the edge.
